BMKG Warns of High Waves Through at Least September 15, 2018
On Tuesday, September 11, 2018, The Metereology, Climate and Geophysics Agency (BMKG) in Denpasar warned that high winds and high waves will persist in the areas surrounding Bali at least through the end of the week.
On Tuesday at Petitenget Beach and at other locations along the island's southern and southwest coasts lifeguards installed "no swimming allowed" flags in various beach locations.
The head of BMKG-Denpasar, Taufik Gunawan, said prevailing weather conditions are cloudy with air temperatures ranging between 22-32 degrees Centigrade with humidity ranging between 58-92%.
Prevailing winds are from the east-southeast at speeds ranging between 8-34 kilometers per hour.
Wave heights in the north of Bali are between 0.5-1.5 meters. Meanwhile, wave heights in South Bali are between 1-3.5 meters and on the Lombok Straits between 0.75-3 meters. Gunawan said current weather conditions are caused by the start of Bali’s dry season with water surface temperatures around Bali ranging between 26-28 degrees Centigrade.
The chief meteorologist for Bali said that Bali’s weather is being influenced by three factors. First, wind speeds over the Indian Ocean at an average 28 kilometers per hour. Second, the winds off the Indian Ocean have sustained their strength for a number of days causing the resulting persistent waves to grow in height. And, third, the large, open ocean areas to Bali’s south allow the strong winds and waves to build over a great distance before coming into contact with the land mass of Bali.
The BMKG is warning the public to exercise caution and be aware of the likelihood of large waves of 2 meters or more striking Bali’s shores, particularly on the Bali Straits, South Bali, Badung Straits, and the southern part of the Lombok Straits.
